Nephelometry is based on the principle of:
Turbidity resulting from specific antigen-coated latex particles agglutinated by
corresponding antibody
Which of the following can cause hemolysis and perhaps result in recollection of
the specimen?
Pushing the plunger of a syringe when transferring blood into vacuum tubes.
A manual white blood cell count was performed by the hematology technologist.
The cell counts for both sides were 99 and 164, respectively. All nine large squares
were counted on each side. The dilution for this kit was pre-measured at 1:100.
What should the technologist report as the white cell count?
Cannot report
When comparing the white cell counts from one side of the hemacytometer to the
other, there is not good duplication. Cell counts from opposite sides of the
hemacytometer (within the same patient sample) that are greater than 10% of one
another are considered discrepant and should not be used to calculate reportable
results. This particular count should not be used to report patient results.

The RBC inclusions shown in the photograph represent which of the following?
Howell-Jolly bodies
Howell-Jolly bodies are usually single, round, and tend to be positioned at the
periphery of the red blood cell. These inclusions are rarely found on a routine
peripheral blood smear, as they are usually removed by a functioning spleen.
Howell-Jolly bodies appear in megaloblastic anemias and after splenectomy.
Which of the following tests would be employed in order to detect neural tube
defects?
Alpha fetoprotein
Alpha-fetoprotein is a protein measured in pregnant women, using maternal blood
or amniotic fluid, as a screening test for a subset developmental abnormalities: it is
principally increased in open neural tube defects and decreased in Down
syndrome.
A patient has the following serum results:
Na = 130 mEq/LK = 4.9 mEq/LCl = 107 mEq/LGlucose = 300 mg/dLBUN = 18
mg/dLCreatinine = 1.1 mg/dL

Which osmolality result is consistent with these results?.
281 mosmol/kg
Osmolality = 2 x Na + [Glucose (mg/dL) / 20] + [BUN (mg/dL)/ 3]
A liquid ion-exchange membrane electrode using the antibiotic valinomycin is
MOST selective for:
Potassium
The valinomycin membrane electrode is most selective for potassium as opposed
to sodium, glucose, or chloride which utilize different membranes for their
respective electrodes. Valinomycin, which is neutral in charge, has been
incorporated into organic liquid membranes resulting in a sensor with a very high
selectivity for potassium.
What should safety management start with in order to ensure clarity and
consistency?
A written safety policy
